Ted Willams

Former ACEC Chair Ted Williams passed away on Monday, June 22, at the age of 71. For 38 of his 50 years in civil engineering, he was at Landmark Engineering, rising to president and chairman of the board. Ted was elected to the ACEC College of Fellows in 2011 and served as ACEC’s national chair the following year. He was inducted into the Order of the Engineer in 2015 and named Delaware Engineer of the Year in 2020.

In 2015, Engineering Inc. featured a profile on Ted’s Flats project, which reimagined a century-old housing development in Wilmington. But the people who worked beside him will tell you his real legacy wasn’t any project. It was the standard he set and the patience he showed teaching others. Ted simply could not say no to a worthy cause and the world is better for that generosity. Everyone who ever worked with him reached for the same words: kind, loyal, supportive. Ted spent his life building things meant to last and looking after the people around him while he did it. That is the finest structure any engineer can leave behind.

ACEC sends our deepest condolences to Ted’s family and friends, particularly his wife, Karen, children Lauren and Ryan, and his three grandchildren. A full obituary can be read here.
